Abstract

This research plan is to introduce the undergraduate student Thales Caldonazo in to basic research in the Experimental Physics area. In particular, the idea is to develop the required background for him to perform Nuclear Magnetic Resonance (NMR) and Nuclear Quadrupolar Resonance (NQR) experiments in Condensed Matter Physics. In that sense, we will be focused on systems and samples mainly related to my Young Researcher Project (JP FAPESP 2012/05903-6) and others of great interest to our research group (GPOMS) in the IFGW-Unicamp. The main goal here is not to restrict the project only to a characterization of a particular physical system of interest but rather to put the student in contact with fundamental details of the NMR and NQR techniques. Thales will get knowledge of the basic theory related to the phenomenon of resonance and will be taught to prepare and assemble samples of distinct morphology on to NMR probes (with goniometer). In this project, the student will also be able to make NMR coils (pick up coils) for tuning the specific Larmor frequency of the nucleous to be observed and will be familiar with an osciloscope and network analyzer, frequently used during the NMR/NQR experiments. Moreover, during the development of this project, it is expected that the student get to learn about the NMR/NQR aquisition softwares - TNMR and MagRes 2000 - and be able to program the rf pulse sequencies for pulse calibration and for the spin-spin (T2) and spin-lattice (T1) relaxation time measurements. Also, the student will be taught to use data analysis softwares such as Origin, Mathematica, Igor, Matlab, etc., always keeping in mind the limitation of a beginner. (AU)
